Objective: To analyze the epidemiological distribution of new occupational pneumoconiosis (hereinafter referred as pneumoconiosis) in Henan Province from 2006 to 2020. Methods: Clinical data of newly recruited pneumoconiosis cases from 2006 to 2020 in Henan Province were retrospectively analyzed. Results: A total of 9 624 cases of newly diagnosed pneumoconiosis were reported in Henan Province in the past 15 years, of which 98.6% were males. The number of cases had two peaks, one in 2009-2011 and the other in 2014-2017. There were 12 types of pneumoconiosis of all reported cases except for mica pneumoconiosis, in which coal workers' pneumoconiosis and silicosis accounted for 96.0%. The incidence of phase Ⅰ, Ⅱ and Ⅲ pneumoconiosis was 64.7%, 21.0% and 14.3%, respectively. The incidence of phase Ⅱ and Ⅲ silicosis was higher than that of coal miners' pneumoconiosis (56.3% vs 22.7%, P<0.01). Patients with pneumoconiosis were mainly distributed in Zhengzhou City, Sanmenxia City, Luoyang City, Pingdingshan City and Hebi City, accounting for 85.0%. The enterprises involved were mainly mining industry, large- and medium-sized enterprises, state-owned enterprises and collective enterprises. The top five position of patients were coal miners, rock drillers, excavators, coal mixed workers and pure coal miners, total accounting for 72.0%. There were 196 enterprises reported ≥10 cases, accounting for 17.2% of all enterprises and 80.3% of the total of newly diagnosed pneumoconiosis cases. The median (M) of onset age of new cases was 49 years old, and the M of onset of working age was 16 years. The onset age of silicosis was younger (M: 49 vs 48 years old, P<0.05), while the onset of working age was longer (M: 10 vs 20 years, P<0.05), compared with that of coal workers' pneumoconiosis. Conclusion: The incidence of pneumoconiosis in Henan Province were disease clustering distribution, regional distribution, industry of enterprise, enterprise scale, enterprise type, nature and working position distribution of enterprises. And it showed the characteristics of group incidence. The prevention and control treatment of pneumoconiosis should be strengthened in key areas, key enterprises and key diseases and jobs.

Shexiang Baoxin pills （SBP） are prescribed based on Suhexiang Pills derived from the Formulary of the Bureau of Taiping People's Welfare Pharmacy （《太平惠民和剂局方》） in the Song Dynasty. As the classic Chinese patent medicine in warming and dredging with aromatics， SBP have been widely used in clinical treatment for 30 years by virtue of their unique efficacy in coronary atherosclerotic heart disease （CHD）. Angiogenesis is a biological process in which the body activates angiogenesis-related factors in the body to act on endothelial cells under local vascular injury， tumor growth， local inflammation， and other stimuli to promote the proliferation， migration， and infiltration of endothelial cells， and form new sprouting or non-sprouting blood vessels. As a new strategy for ischemic diseases such as CHD， therapeutic angiogenesis is of great significance in the prevention and treatment of CHD in promoting angiogenesis of ischemic myocardium and establishing effective collateral circulation. However， for the atherosclerotic plaque and tumor， angiogenesis promotion is a risk factor for accelerating the disease progression. Therefore， safe and effective regulation of ischemic myocardial angiogenesis has become the focus of the current prevention and treatment of CHD. Studies in recent years have shown that SBP can intervene in angiogenesis with multiple pathways and targets， which can exert therapeutic angiogenesis effect on CHD and also inhibit atherosclerotic plaque and tumor angiogenesis to varying degrees. This study reviewed the experimental and clinical trials on the regulatory effect of SBPs on angiogenesis in CHD to provide references for the research on Chinese medicine intervention in angiogenesis of CHD.
